Canister Filter or??

[Koresample]

ok, so just use it as an (expensive) powerhead. I dont have an RO/DI unit so i use the phosphate/Silicate removal stuff (change that once per month is my planned schedule). Should i also get rid of the sponge filters from it as well?

I would strongly recommend getting a RO/DI unit. Pretty much a necessity in any reef tank.

Yes indeed, most certainly remove sponges or anything that could possible catch debris. And do clean knead the bags that your chemical media is in, if it is in bags, daily to remove any sediment that may have gotten caught in it.
